"I think anybody who has played the game for 20, 25 years, four or five times in their career, always thought about not playing anymore," said Quinn.

"I play because I love the game. I know that I have the ability to compete. I love competing. And I love the challenge every day of going out and trying to beat the best players in the world."

Quinn is a Northwestern graduate (class of 1987) and actually has eight professional wins. But you have to think a top 10 or better this weekend at the US Open with his 15-year-old son caddying for him would be his career highlight.

"It's surreal," he said. "To be able to have your 15 year old out with you, walking on the biggest stage in the world. We've talked about it and he's handled it far better than I would have at 15 years old."
